Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • OCI NAT Gateway.

    Why it's wrong here

    A NAT Gateway allows private resources to initiate outbound connections to the internet, but does not provide secure inbound administrative access.

  • OCI Load Balancer with TCP routing.

    Why it's wrong here

    A Load Balancer distributes incoming application traffic, not secure administrative terminal access.

  • OCI API Gateway.

    Why it's wrong here

    API Gateway is designed to publish, secure, and route REST APIs, not provide SSH terminal access to compute nodes.

  • OCI Bastion service.

    Why this is correct

    OCI Bastion provides secure, audited, and time-bound access to private compute instances without public IP addresses.
